Started putting my Bulgarian ak 74 together finally. I used the udrives and on the inside of the receiver I migged the ends on some udrives to the trunions. The only u drives I couldn't get where behind the barrel which got red locktight and the upper rear truinion screws (2) The lower rear trunion I migged. So two in the back lower trunion got migged and two in front lower trunion. So I am wondering if this is a method people used or could use to stop the fear of u drive failure? If I read right the back Udrives failing is what supposedly hurt the guy in the forums? With them migged in they are going no where. |
| I built a Yugo with U drive screws and the screws have held up after a few hundred rounds. I didn't MIG weld the ends I just hammered them in and if you see the tutorial in the forum the guys who built using U drive screw have shot a few thousand rounds in theirs. I would have probably also shot more rounds but availability and price increases have forced me to shoot .22s. I had to grind off the screw ends where near the magazine well to allow for magazine insertion. |
